so here i'm trying to to update quantity in product_inventory table that links between products and inventories,
however it's updated in the database but not in the screen until i use ctrl S.
i tried to use many possible ways as calling the quantity in different way even in setState but none of them worked,
how can i make the data change after the quantity update.
also i'm using an API with laravel
class ProductsInInventoryWidget extends StatefulWidget
{
ProductsInInventory? model;
BuildContext? context;
//final ValueChanged onPressed;
ProductsInInventoryWidget({this.model,this.context});
@override
_ProductsInInventoryWidgetState createState() => _ProductsInInventoryWidgetState();
}
class _ProductsInInventoryWidgetState extends State<ProductsInInventoryWidget> {
var apiCall = new APICall();
addQuantity(String mydata) async
{
String Product_BarCode = widget.model!.productBarcode.toString();
String Inventory_id = widget.model!.inventoryId.toString();
var response = await http.put(
Uri.parse("http://192.168.1.188:8000/api/user/IncrementProduct/" Product_BarCode "/" Inventory_id,),
body:jsonEncode(<String, String>{
'quantity': mydata,
}),
);
// setState(() {
// response;
// mydata = widget.model!.quantity.toString();
// });
}
@override
Widget build(BuildContext context) {
var quantityData = widget.model!.quantity.toString();
return InkWell(
onTap: ()
{
// Navigator.push(context, MaterialPageRoute(builder: (c)=> ProductsInInventoryForm(model: widget.model)));
},
splashColor: Colors.amber,

children: [

onPressed: ()async {
onRefresh: () { setState((){
// Update your data here
addQuantity(quantityData);
}); };
setState(() {
// widget.onPressed;

}
}
CodePudding user response：
Future addQuantity(String mydata) async
{
String Product_BarCode = widget.model!.productBarcode.toString();
String Inventory_id = widget.model!.inventoryId.toString();
var response = await http.put(
Uri.parse("http://192.168.1.188:8000/api/user/IncrementProduct/" Product_BarCode "/" Inventory_id,),
body:jsonEncode(<String, String>{
'quantity': mydata,
}),
);
// setState(() {
// response;
// mydata = widget.model!.quantity.toString();
// });
}
and call method like that
await addQuantity(quantityData);

here I did some steps on how you can resolve the issue, check the comments steps:
class _ProductsInInventoryWidgetState extends State<ProductsInInventoryWidget> {
var apiCall = new APICall();
String? quantityData; // <--- 1# add this variable here
Future<void> addQuantity(String mydata) async
{
String Product_BarCode = widget.model!.productBarcode.toString();
String Inventory_id = widget.model!.inventoryId.toString();
var response = await http.put(
Uri.parse("http://192.168.1.188:8000/api/user/IncrementProduct/" Product_BarCode "/" Inventory_id,),
body:jsonEncode(<String, String>{
'quantity': mydata,
}),
);
setState(() {
// quantityData = responseResult 6# Finally you should assing the new response data from the Laravel to quantityData variable
// I do not know how you are receiving this data so get the response a them add it gere.
});
}
@override
void initState() {
// TODO: implement initState
quantityData = widget.model!.quantity.toString(); // 2# assign the incoming data here
super.initState();
}
@override
Widget build(BuildContext context) {
return InkWell(
onTap: ()
{
// Navigator.push(context, MaterialPageRoute(builder: (c)=> ProductsInInventoryForm(model: widget.model)));
